Foreword
This document (prEN 10358:2012) has been prepared by Technical Committee ECISS/TC 110 “Steel tubes,
and iron and steel fittings”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
1 Scope
This European Standard specifies materials and test requirements for tube connections with press fittings
made of unalloyed steel.
This European Standard specifies press fittings in the size range 12 mm to 108 mm for the purpose of joining
unalloyed steel tubes intended for use in heating and cooling systems, wet sprinkler systems, oil transporting
and compressed air.
Permissible operating temperatures and maximum operating pressures are also established.
Fittings may comprise a combination of end types, specified in this standard or other standards, providing they
are suitable for the fluid /air being conveyed.
The standard establishes a designation tube system with press end joints made with the components fitting
and tube, pressed with a pressing tool.
This standard is applicable to press fittings for joining unalloyed steel tubes to EN 10305-3, EN ISO 2081,
EN 10346.
Fittings may be suitable for joining other metallic tubes provided the press fitting joint with the specified tube
meets the requirements of this standard.
